Magnetic fields may be invisible but they are all around us with different strengths. In this lesson we’ll see how a hall effect sensor can be used to detect a magnetic field and be used as a magnetic motor encoder.

Motion detection is vital for most security systems and the PIR motion sensor is a popular choice in that area. In this lesson we will learn how the PIR motion sensor works and how we can use it to set off an alarm when motion is detected.

In today’s PyroEDU lesson we continue with our new course: An Introduction To Sensors and take a look at how to sense light. Light Sensors like the photoresistor and photocell are very important and use throughout society. In this lesson we will go through the theory about photoresistors and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

Light is an element that is crucial for life on earth and it is also something we can easily sense electronically. In this lesson we will use a photoresistor to detect changes in brightness by making a laser trip-line.

Today we delve a little deeper into object detection with proximity sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Ultrasonic Proximity Sensors and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

Proximity detection is important for any application that needs to know if an object has crossed a sensor’s path. In this lesson we will learn how to use an ultrasonic proximity sensor to detect how far away an object is.

This week we are learning how to detect sound in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Sound Sensors and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

We all hear and use sound in our daily lives, so we must also learn how to detect sound electronically. In this lesson we will use an electret microphone to convert sound from an acoustic wave, into an electrical signal.

Today we are learning about infrared encoder sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Infrared Encoders and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

Detecting changes in color and reflectivity can be achieved using an infrared emitter and phototransistor. In this lesson we’ll do just that by making a rotary encoder for tracking a motor’s movement.

This week we are learning about proximity sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about IR Proximity Sensors. Here’s a quick intro of what this PyroEDU lesson is all about:

Knowing if something is in front of you is very useful for many different electronic applications. In this lesson we will use an infrared emitter and detector to sense if an object has crossed the sensor’s path.

Today we are learning about temperature sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Temperature Sensors and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

The temperature sensor is a small component that packs a powerful punch. In this lesson, we’ll use a temperature sensor to output the current temperature inside the range of -40°C to +125°C.

This week we’re diving into tilt sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Tilt Sensors and perform a simple experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

The mechanical tilt sensor is one of the most basic types of sensors available. In this lesson we will learn how the tilt sensor uses some conductive balls to detect when the sensor has passed ± 90° of tilt.
